The invention relates to a sampling devvice for taking core samples of material from va bulk todeterniine the characteristics'of the bulk. i

- fTh'e device was developed when the need of accurately determining thernature 'of a river bed was presented. Methods then` known allowed for too much. slipping of material from different levelsinto the sampler; the .stratificationof the material'could not: be found.v` With my device the actual, un-

disturbed, 'stratificatiom and nature 'of the' i material can be determined. The objects of my invention aret'o make a sainpler that inay be driven into the material closed, to a given deptli, that'may then beopened to receive.

a sample, at one or more 'levels, that has means to draw material into Athe pockets provided in the sampler, that may be closed V and removed and the sample removed without danger of admixturej with other mate rials, that has means to prevent serious breakage tothe device should hard obstrucv tions be encountered.. Other objects and advantages will be apparent as the description of the device proceeds.

throughout the several views. i

Outer4 tube 1 has therein a plurality of ii 40 openings 2 extending longitudinally of thetube and not quite half way around it, n inner tube 3 has similar openings 4 in its walls. These several openings in both tubes,v

are preferably placed angularly from each other` around the tubes to give the tubes formed inthe tube. Within these pockets,

cups :G ,areremovably placed, having a hol'e 7 ,lefitting overfa pin '8,inithe lower block 5" of the pocket,'to[prevent rjot'ation or falling out. Clip 9, on each cup, is snapped under a shoulder of innerftube 3, to hold the cup vsecurely in place.

Cutter .fiaps 10 are s'ep'rve: to dig into the material'in V'fillin'g' and to .direct the material into the pockets.
